El RFC recibi\u00f3 el estatus de \u00abEst\u00e1ndar Propuesto\u00bb, tras lo cual comenzar\u00e1 el trabajo para otorgarle al RFC el estatus de Est\u00e1ndar Borrador (Draft Standard), lo que significa la estabilizaci\u00f3n completa del protocolo y la consideraci\u00f3n de todas las observaciones realizadas.<\/p>\n<p>El mecanismo \u00abDNS Push Notification\u00bb permite al cliente recibir notificaciones del servidor DNS sobre cambios en los registros DNS de forma as\u00edncrona, sin necesidad de consultar peri\u00f3dicamente. Las notificaciones Push se procesan \u00fanicamente utilizando el transporte TCP con protecci\u00f3n de canal a trav\u00e9s de \u00abTLS over TCP\u00bb. Un servidor DNS autoritativo puede aceptar conexiones TCP de clientes de DNS Push Notification que env\u00edan solicitudes de suscripci\u00f3n a ciertos nombres y tipos de registros DNS. Despu\u00e9s de recibir la solicitud de suscripci\u00f3n, el servidor enviar\u00e1 notificaciones al cliente sobre los cambios en los registros especificados. <\/p>\n<p>El cliente determina la presencia de soporte para DNS Push Notification enviando una solicitud DNS normal que verifica la existencia del registro SRV \u00ab_dns-push-tls._tcp.nombre_de_zona\u00bb, que indica los servidores DNS que gestionan las suscripciones. El cliente tambi\u00e9n puede suscribirse a un registro inexistente, y el servidor debe notificar al cliente si aparece en el futuro. Las notificaciones se env\u00edan solo cuando hay una conexi\u00f3n TCP establecida con el servidor y no est\u00e1n destinadas a un seguimiento 24 horas al d\u00eda, 7 d\u00edas a la semana; la suscripci\u00f3n debe cancelarse en caso de inactividad (por ejemplo, cuando el dispositivo entra en modo de espera) y utilizarse solo cuando sea necesario para el seguimiento de cambios en tiempo real. A trav\u00e9s del canal TCP establecido para las notificaciones Push, tambi\u00e9n se pueden enviar solicitudes DSN normales.<\/p>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Fuente: <a \ncontent=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=53276\">opennet.ru<\/a><\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041a\u043e\u043c\u0438\u0442\u0435\u0442 IETF (Internet Engineering Task Force), \u0437\u0430\u043d\u0438\u043c\u0430\u044e\u0449\u0438\u0439\u0441\u044f \u0440\u0430\u0437\u0432\u0438\u0442\u0438\u0435\u043c \u043f\u0440\u043e\u0442\u043e\u043a\u043e\u043b\u043e\u0432 \u0438 \u0430\u0440\u0445\u0438\u0442\u0435\u043a\u0442\u0443\u0440\u044b \u0438\u043d\u0442\u0435\u0440\u043d\u0435\u0442\u0430, \u0437\u0430\u0432\u0435\u0440\u0448\u0438\u043b \u0444\u043e\u0440\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u0435 RFC \u0434\u043b\u044f \u043c\u0435\u0445\u0430\u043d\u0438\u0437\u043c\u0430 &#171;DNS Push Notifications&#187; \u0438 \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043b \u0441\u0432\u044f\u0437\u0430\u043d\u043d\u0443\u044e \u0441 \u043d\u0438\u043c \u0441\u043f\u0435\u0446\u0438\u0444\u0438\u043a\u0430\u0446\u0438\u044e \u043f\u043e\u0434 \u0438\u0434\u0435\u043d\u0442\u0438\u0444\u0438\u043a\u0430\u0442\u043e\u0440\u043e\u043c RFC 8765.
